Ac equivalent circuit?

Hello All,

I am beginner in electronics
I wish to know why do we need to do DC analysis and ac analysis of a
circuit?
As a rule , what component or node we must short to gnd for ac
equivalent circuit?
Then for DC analysis, what are the rule of thumb?
Please let me know in step by step. Or any online document you can
share

Also if input is voltage source or current source which I do not know
if it is ac or dc type, what should I do with them when I draw an ac or
dc equivalent circuit?

Kindly help
thanks

Jason

Hi Jason, try this:

Hi Mark

May I know which part of the book will be able to answer my enquiries?
I am not too sure which one I should check it out.
Kindly advise

Jason, as a beginner, I suggest you start at the beginning and work
forward.

As you have yet to understand why we do DC (sometimes called large
signal) analysis and AC (small signal) analysis, I suggest you read the
first two sections to start (DC and AC). There's no issue with you
being a beginner (we all were at one point :) Just keep in mind that
one can work in this stuff for years (>35 years personally) and still
learn new and interesting things about circuit analysis.

Slightly OT, but sci.electronics.basics will tend to get you more
answers :)

Cheers
